Isolated RS-232 to RS-485 Signaling Converter

This project provides a solution for converting RS232 signaling to RS485 signaling. This allows long-distance communication since the range supported by RS232 is normally less than 50 feet while RS485’s range can exceed 1000 feet. The design features an RS232 transceiver, an RS485...
